System Utilities

This set of utilities exposes some of Raycast's native functionality to allow deep integration into the user's setup. For example, you can use the Application APIs to check if a desktop application is installed and then provide an action to deep-link into it.

API Reference

getApplications

Returns all applications that can open the file.

Signature

async function getApplications(path?: PathLike): Promise<Application[]>;

Example

Find Application
List Installed Applications
import { getApplications, Application } from "@raycast/api";
// it is a lot more reliable to get an app by its bundle ID than its path
async function findApplication(bundleId: string): Application | undefined {
const installedApplications = await getApplications();
return installedApplications.filter((application) => application.bundleId == bundleId);
}
import { getApplications } from "@raycast/api";
export default async function Command() {
const installedApplications = await getApplications();
console.log("The following applications are installed on your Mac:");
console.log(installedApplications.map((a) => a.name).join(", "));
}

Parameters

Name
Description
Type
path
The path of the file or folder to get the applications for. If no path is specified, all installed applications are returned.
PathLike

Return

An array of Application.

getDefaultApplication

Returns the default application that the file would be opened with.

Signature

async function getDefaultApplication(path: PathLike): Promise<Application>;

Example

import { getDefaultApplication } from "@raycast/api";
export default async function Command() {
const defaultApplication = await getDefaultApplication(__filename);
console.log(`Default application for JavaScript is: ${defaultApplication.name}`);
}

Parameters

Name
Description
Type
path*
The path of the file or folder to get the default application for.
PathLike

Return

A Promise that resolves with the default Application that would open the file. If no application was found, the promise will be rejected.

getFrontmostApplication

Returns the frontmost application.

Signature

async function getFrontmostApplication(): Promise<Application>;

Example

import { getFrontmostApplication } from "@raycast/api";
export default async function Command() => {
const defaultApplication = await getFrontmostApplication();
console.log(`The frontmost application is: ${frontmostApplication.name}`);
};

Return

A Promise that resolves with the frontmost Application. If no application was found, the promise will be rejected.

showInFinder

Shows a file or directory in the Finder.

Signature

async function showInFinder(path: PathLike): Promise<void>;

Example

import { showInFinder } from "@raycast/api";
import { homedir } from "os";
import { join } from "path";
export default async function Command() {
await showInFinder(join(homedir(), "Downloads"));
}

Parameters

Name
Description
Type
path*
The path to show in the Finder.
PathLike

Return

A Promise that resolves when the item is revealed in the Finder.

trash

Moves a file or directory to the Trash.

Signature

async function trash(path: PathLike | PathLike[]): Promise<void>;

Example

import { trash } from "@raycast/api";
import { writeFile } from "fs/promises";
import { homedir } from "os";
import { join } from "path";
export default async function Command() {
const file = join(homedir(), "Desktop", "yolo.txt");
await writeFile(file, "I will be deleted soon!");
await trash(file);
}

Parameters

Name
Description
Type

Return

A Promise that resolves when all files are moved to the trash.

}

Parameters
